Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 33,177,395, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 33,177,395 | |
| -1 | -33,177,395 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,177,395.
Example:
1 x 33,177,395 = 33,177,395
and
-1 x -33,177,395 = 33,177,395
Notice both answers equal 33,177,395
With that explanation out of the way, let's continue. Next, we take the number 33,177,395 and divide it by 2:
33,177,395 ÷ 2 = 16,588,697.5
If the quotient is a whole number, then 2 and 16,588,697.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 33,177,395 | |
| -1 | -33,177,395 |
Now, we try dividing 33,177,395 by 3:
33,177,395 ÷ 3 = 11,059,131.6667
If the quotient is a whole number, then 3 and 11,059,131.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 33,177,395 | |
| -1 | -33,177,395 |
Let's try dividing by 4:
33,177,395 ÷ 4 = 8,294,348.75
If the quotient is a whole number, then 4 and 8,294,348.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 33,177,395 | |
| -1 | 33,177,395 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 97 | 335 | 485 | 1,021 | 5,105 | 6,499 | 32,495 | 68,407 | 99,037 | 342,035 | 495,185 | 6,635,479 | 33,177,395 |
| -1 | -5 | -67 | -97 | -335 | -485 | -1,021 | -5,105 | -6,499 | -32,495 | -68,407 | -99,037 | -342,035 | -495,185 | -6,635,479 | -33,177,395 |
